STOPPER. I

Specification of Letters Patent.

' Patented Sept. 26, 1905.

Application filed November 25, 1904. Serial No- 234,170.

pecially to that type of stopper commonly used with hot-water bottles.

Itis the object of our invention, among other things, to construct a stopper wherein the bot tle can be filled without separating the plug from the stopper-body, as well as to so design the parts that they can be economically constructed, and thus produced at the minimum cost.

To these and other ends our invention consists in the stopper having certain details of construction and combination of parts, as will be hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures, Figure 1 is an elevation of our improved stopper complete. Fig. 2 is a fragmentary sectional view thereof; showing also a sectional elevation of the neck of the bottle; and Fig. 3 is a fragmentary sectional elevation of the plug.

Heretofore in all of the stoppers used for hot-water bottles it has been necessary to remove the plug when filling the bottle. This construction is objectionable in that it necessitates the separation of the plug and bottle between the ends thereof and turned inwardly at its bottom end to form a seat 2, upon which rests a rubber. gasket 3. This body member is secured within the neck of the water-bottle 4 in any of the many ways common to the art. Threaded within said body member is the plug'6, having the head 8 at one end and terminating at its other end in a finger-piece 7. Upon the top of said body member is threaded the cap 9, having the in.

wardly-turned lip 11 with a hole therethrough of a diameter less than that of the plug-head 8 and of metal thinner than the space between the threads upon said head. This lip will permit the head 8 to be worked through the cap before it engages the body memberand effectually prevents its withdrawal from the said bodymemb'er after the cap is placed in position. It is apparent that a lip can be formed on the top of the body member after the plug is threaded therein and perform the same function as the lip when part of the cap.

In operation the liquid is poured into the throat 4 of the hot-water bottle, which acts as a funnel, and passes through the port-holes 5 'into the bottle, and after the-same is filled or the desired quantity has been admitted the plug is rotated by the finger-piece 7 until the head 8 is brought down upon the rubber gas ket 3, and during its rotation and endwise movement it passes the holes 5 and when seated is below the same, so that no liquid can pass either in or out of said bottle.

To empty the bottle, the rotary movement of the plug is reversed, which uncovers the port-holes 5, permitting the contents to escape therethrough.

If desired, a rubber block 10 can be fixed within the head 8 of the plug, Fig. 3, in lieu of the rubber gasket 3.

There are minor changes and alterations that can be made within our invention aside from those herein shown and suggested, and we would therefore have it understood that we do not limit ourselves to the exact construction herein shown and described, but claim all that falls fairly Within the spirit and scope of our invention.

Having described our invention, what we claim as new, and desire to secure by Letters I at one end thereof; a plug movable parallel with the axis of said body member toward and away from said seat and adapted during said movement to cover and uncover said porthole; and a cap connected with said body member having a lip thereon of less thickness than the space between the threads on said plug, and a hole therethrough of less diameter than thehead of said plug but greater than the diameter thereof at the bottom of the threads thereon, for limiting the movement of said plug in one direction.

2. In combination with a water bottle, a stopper aflixed thereto composed of a body member having an opening therethrough at its inner end within said bottle and a radial port through the side thereof outside of said bottle; a threaded plug movable within said body member and adapted to cover and uncover said opening and port during its movement; and a cap, connected with said body member, having a hole therethrough of less diameter than thehead of said plug but greater than the diameter thereof at the bottom of the threads thereon for limiting the movementol said plug in one direction.

In a stopper, the combination with the cylyndrical body member 1, having a spirallycorrugated shell, which corrugations form both an internal and external thread, and portholes 5 passing radially through said body member; of a plug 6, the head 8 of which is externally threaded and movable parallel with the axis of said body member; and a cap 9 with the lip 11 thereon threadably secured to one end of said body member and having a lip 11 thereon of less thickness than the open space between the threads upon said head 8, all constructed and operated substantially as described.

In testimony whereof we aiiix our signatures in presence of two witnesses.
